TELESCOPIC UMBRELLA.

Application led June 20,`

' l- This invention' relates to an umbrella of the kind whereinl thehandle, the sta-ff and the ribs are formed with telescopicallyadjustable parts and wherein the hollow handle telescopes between theribs and the stretchers, and the invention consists essentially inarranging the spring catch which retains the rib parts in extendedposition, close to the joint between the rib andthe stretcher so as tobe positively engaged and released by the latter when the umbrella isfolded. The invention includes other details of construct-ion andcombination of parts made with a View to simplify the frame andfacilitate the operation of folding and extending the same.

The umbrella has a staH composed of three telescopically connected parts1, 2 and 3 of which the latter is secured by means of a pin 8 to thebottom of the hollow handle 4. The part 2, which telescopes outside thepart 3, has at its lower end a piston 6 whereby it is guided within thehandle 4.l The piston has a groove 7 in which a projection situatedwit-hin the handle, engages for preventing rotary displacement betweenthe parts. Connected to the piston 6 is a washer formed with catches 5which may be pushed into the -handle but which are adapted to engageover the edge of the same, as shown in Fig. 1, for retaining the part 2in extended position. r1he art 1 moves outside the part 2 and isretained on the latter in' extended position by means of a latch 9supported by a spring located inside the part 2. The edge of the part 1is notched as shown at 10 lfor engagement with the latch 9 and forpreventing rotary displacement. The part 3 has a part 13 which isslidable on the inner part.

pin 11 adapted to enter Ibehind the spring of the latch 9 so as torelease the latter when i the parts are pushed together.

- The runner is arrested by means of two spring catches`21 and 22 formedby the splitting of a sleeve 20 secured to the partnl. These catchesclose round the staifto let ythe runner pass and do not for thisi-trpose have to enter the tube. The edges 23 and 24 of the catches arecut aslant so that the catches can easily be slipped in betweenthe'runner vand the staff.l The runner 19 is undercut, as

shown at 25 (Fig. 6), for the reception of the catches which arethereby""prevented from excessive spreading under the pressure of theextended cover.

'1` he ribs are composed of an inner part 14 which Vis pivoted to thecrown 12, and an outer The part'13 is formed at its inner end with lugs17 to which the stretcher 18 is pivoted. The rib parts are guided onthe' one hand by a collar 15 which is rigidly secured to the outer endof the part 14, and on the other hand by a clip 16 which embraces thetwo parts at opposite sides of the lugs 17 and which follows the part 13up and down the part 14. rIhe clip 16' is adapted for connection to thecover 31, as shown in Fi 2, and is loose enough to allow'of being he ddown by the cover in a non-protruding position. A spring 29 which bendsaboutv the pivot of the stretcher 18, bears against the latter andagainst the clip 16 and tends to-open out the frame when the umbrella isclosed. A catch 27 carried by a spring 26 on the part 13, snaps intoengagement with theeollar 15 f for locking the rib arts in extendedposition. The spring 26 1s prolonged beyond the catch and bent off so asto form a projecting lug 28 ladapted to abuta ainst the stretcher ner 19in the usual manner. At least one of the stretchers is provided with aresilient arm 30 which is fastened to the same near the runner and whichdiverges slightly from the stretcher. This arm bears against the ribpart 13 when the umbrella is closed, and its free end is then situatedunder the collar 15, as shown in Fig. 4, so as to engage the latter andretain the ribs normally in extended position until the catches 27 vhavebeen released during the opening of the umbrella. Normally, therefore,the umbrella can be opened and closed in the usual manner.

When it is desired to reduce the umbrella to its small size, whichisdone when the umbrella is closed, the catches 5 are depressed so as toallow the stati' part 2 to be pushed into the handle 4. The handle slipsover the stretchers 18 and depresses the arm or arms 30 so as to preventthem from engaging the co1- lars 15. It also presses the stretchersagainst the staff and causes the catches 27 t0 be positively released'from the collars. \Thus, when the latch 9 has beenl engaged andreleased by the pin 11 and when the staff part 1 is pushed down over thepart 2, the catches 27 are able to slip through the collars 15 and allowthe ribs to be contracted together with the staff. In the reducedposition lof the umbrella, shown in Fig. 2, the cover 81 forms a fold32.

To extend the umbrella for use, the handle is simply pulled out until itis disengaged by ythe eatches, the ribs being at the same time extendedto their normal positions and locked by the catches 27 when the umbrellais opened.

A ring 33, which is retained on the handle 4 when the umbrella is inuse, is adapted to be pushed over the stretehers 30 to hold the frame inclosed positon.

lf claim:

1. In an umbrella ofthe character described, the combination of atelescopic staff, a hollow handle to which one part of the stati isrigidly connected, a piston whereby another part ot' the staff is guidedWithin the handle, ribs divided into two telescopically adjustableparts, stretchers pivoted to the inner ends of the outer rib parts, arunner on the staff holding the stretchers and adapted to enter the`handle together with the stretchers, and

spring catches carried by the outer rib parts adapt-ed to lock the ribparts in extended position, said catches being adapted when thestretchers enter the handle, to be clamped against said stretchers underthe influence of the handle so as to be released and enable thestretchers, the outer rib parts and the catches to be displaced togetherrelative to the inner rib parts.

2. The structure claimed in claim 1 and a resilient stop connectedto thestretcher and adapted, by engagemenhwith one of the rib parts to preventnormally the ribs from being contracted when the catches are released,the handle being adapted on the reception of the stretchers, to engagesaid stop and render it inoperative.

3. The structure claimed in claim 1 in combination with a resilient armconnected to a stretcher so as to place itself against the adjacentribwhen the umbrella is closed, and an abutment arranged so as to beengaged by said arm for preventing normally the ribs from beingcontracted when the catches are released, the handle being adapted, onthe reception of the stretcher, to engagesaid arm and render itinoperative l. The structure claimed in claim 1 and a clip embracing therib parts as a guide for the same and arranged so as to follow the outery rib part, said clip beinglooped for connection to the umbrella coverand held down by the latter in a non-protruding position.

5. The structure claimed in claim 1 in combination with a sleeve securedto one of the stati? parts so as tobe passed by the runner, said` sleevebeing split into resilient parts which are spread apart so as to act ascatches l for the runner after the latter has passed the sleeve.

6. rl`he structure claimed in claim 1 in combination with springsapplied to the outside of the stati and bent off from the latter so asto act as catches for the runner, the springs being adaptedto be pressedagainst the staff when passed by the runner, the runner beingprovidedwith a recess in which the catches are adapted to engage whensupporting the runner. 4

v7. The structure claimed in claim 1 in eom bination with a washerapplied to the piston, and spring cat-ches formed integrally with saidwasher and adapted to engage over the edge of the handle so as'to retainthe corresponding sta part in extended position.
